Abstract: 1455576 Microcapsules WIGGINS TEAPE Ltd 30 May 1974 [7 June 1973] 27281/73 Heading B8C A method of producing individual mononuclear oil-containing microcapsules comprises emulsifying an oil in a solution of a gellable hydrophilic colloid (e.g. an aqueous solution of gelatin), adding a solution of carboxymethyl cellulose to the emulsion, effecting complex coacervation so as to form mononuclear microcapsules each comprising a droplet of the oil as a nucleus with a wall of the colloid material and carboxymethyl cellulose around the nucleus, and gelling the microcapsule walls, the dry weight ratio of the colloid material to active content of the carboxymethyl cellulose used being between 1 : 0À35 and 1 : 1À2. The use of methyl cellulose and carboxymethyl cellulose in a ratio of 1 : 1, and also the use of gelatin and carboxymethyl cellulose in a ratio of 1 : 0À5, are disclaimed. The oil may be a mineral oil (e.g. kerosene) or a synthetic oil such as alkylated diarylmethanes, di-isopropyl naphthalene, mono-isopropyl biphenyl, dibenzyl benzenes, heptyl undecyl phthalate, alkylated diarylethanes and alkylated benzenes. Kerosene of alkylated benzene may be used as diluents for other synthetic oils and in the examples partially hydrogenated terphenyl diluted with kerosene is employed. Complex coacervation is effected in the examples, after adding carboxymethyl cellulose to the emulsion of oil in aqueous gelatin solution, by lowering the pH of the mixture from 7À5 to 4À4 by addition of acetic acid, followed by cooling of the mixture from 55 to 10‹ C. Glutaroldehyde solution is then added, the mixture stirred overnight, the pH then raised to 10 by addition of sodium carbonate solution and finally forwaldehyde solution is added. The oil employed may contain dissolved dye and the microcapsules produced may be coated on to a paper base for use in a pressure-sensitive copying system.

Abstract: An accelerometer is provided which comprises a pendulum rotatable about an axis and which is arranged for measuring vertical angles. A rotatable device which is preferably of the moving coil type is located at the axis of rotation of the pendulum. The rotational device preferably comprises magnet arrangement for providing a constant magnetic field, and a movable coil which supports the pendulum for rotation and is rotatable in the magnetic field. The angle to be determined is measured by rotating the magnet arrangement about the axis from a reference position to the desired angular position and thereafter supplying current through the coil of such strength and polarity that the coil, and thus the pendulum is rotated about the axis of rotation from the vertical reference position it would normally assume due to the forces of gravity to the angular position of the magnet arrangement. The current required to effect such rotation of the pendulum is proportional to the angle to be measured.

Abstract: An electronic regulator produces a regulated direct voltage less than the raw direct voltage input. The load on the regulated output is the primary winding of the horizontal output transformer of a television horizontal deflection circuit. A secondary winding of the output transformer is connected in series with the source of raw direct voltage. An energy storage capacitor is coupled across the secondary winding, and charged therefrom by a gated rectifier. The regulated output voltage is taken across the raw direct voltage source and capacitor. An overvoltage protection circuit for protecting against fault conditions is provided. The protection circuit includes a diode coupled between the regulated output voltage terminal and the raw input voltage terminal. The diode is normally back-biased and becomes conductive when a fault condition makes the regulated voltage exceed the raw input voltage. A resistor in series with the secondary winding controls circulating currents in the event of an overvoltage fault.

Abstract: The invention concerns a procedure for calculating the remaining billet length of rolled material. Two time measurements are performed along the rolling trajectory, an earlier one in the rolling trajectory P1 and a later one in the trajectory P2, situated after the last pair of rolls, wherein the time measurements T1 and T2 are started when the front end of the billet passes the particular time measurement point and the difference between these time measurements T1-T2 is read off when the rear end of the billet passes the first time measurement point P1. After this, the estimated remaining billet length is calculated in its final dimension by multiplying the time difference by a measured travel speed VM2 for the billet N at the second time measuring point P2, and the amount LA thus obtained is corrected with regard to the exact corresponding length LB and the estimated length measured during the rolling of the preceding billet N-1. <IMAGE>

Abstract: Large current gains and high degrees of sensitivity to impinging primary photons are realized in photon feedback photodetectors embodying the invention. A photocurrent generated by an internal photodiode (10, 11) in response to the primary photons (6) causes secondary photons to be emitted by internal serially connected luminescence diodes (12, 13; 14, 15). Secondary photons traveling away from the photodiode are redirected by a reflector (16) to impinge on the photodiode and thereby sustain the photocurrent. Gains of the order of 100 are realized by these photodetectors.

Abstract: The manufacture of non-returnable packages for e.g. milk is frequently carried out by the conversion of web-shaped, laminated packing material to a tube, filling of the tube with milk, and sealing and forming to filled packing containers of the desired, e.g. parallelepipedic, shape. For the forming, which is done by means of external forming devices, the contents are made use of as a holder-up for the forming device pressed-on from the outside, so that the desired shape can be achieved without creasing or other deformations.The abovementioned forming principle works less well if the packing containers are not completely filled, but have a certain air space, so-called headspace. The proportioning of the contents also becomes uncertain and the desired accuracy of volume cannot always be achieved. These difficulties are overcome in that a sealed off part of the packing material tube is pressurized with the help of gas during the forming process, so that the internal back pressure required during the forming is obtained, independently of the quantity of contents. The method also permits an accurate proportioning of the contents either by continuous feed at a controlled flow rate or by discontinuous feeding in portions. The invention also relates to an arrangement for the realization of the method.

Abstract: On an intermediate shaft connected to a propeller shaft there are supported a stationary housing and a distributor or separator ring structure limiting two annular passages in the housing which can be selectively impinged with pressurized oil. The annular passages are connected to two oppositely effective working spaces of a servo motor of the adjustable pitch propeller by control passages extending through the intermediate shaft and the propeller shaft. The separator or distributor ring structure comprises axial sections, each of which is formed of one part in circumferential direction and is fixedly connected in axial direction to an axial section thereof associated with the same annular passage by web or bridging members bendable in radial direction. Each axial section is sealingly guided in a cylindrical bore of the housing by a respective sealing ledge protruding from the outer circumferential face thereof. Such arrangement permits elastic deformations of the axial sections in the sense of constricting bearing gaps or clearances formed with the intermediate shaft. Thus, the sealing action thereof is improved. Also, the parts of the housing surrounding the intermediate shaft thus can be formed of one-piece in circumferential direction, thereby requiring only modest machining and assembly work.
